From 4.0.0 until 4.16.1, ZITADEL Login V2 creates a browser session after password verification and can reuse that session for a later authentication request without verifying a user's enrolled TOTP, OTP, or U2F second factor. When the MFA step is abandoned and login starts again, session-validity checks require MFA only when the organization enables Force MFA or Force MFA for local users only, so a voluntarily enrolled factor can be skipped while completing an OIDC or SAML callback for a customer application. Login V1, the ZITADEL Console, Management and Admin APIs, and user self-management are not affected. This issue is fixed in version 4.16.1.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N","score":8.2,"severity":null}],"references":["https://github.com/zitadel/zitadel/security/advisories/GHSA-9993-rfwp-rhwf","https://github.com/zitadel/zitadel/commit/049dbb25a56587fb3980c85c99819cad69f637db","https://github.com/zitadel/zitadel/commit/56f4798ed31fc1cfcd9a0e7f6f0152289d2fdc43","https://github.com/zitadel/zitadel/releases/tag/v4.16.1"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-86324","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 24, 2026, 5:34:13 PM","dateUpdated":"Sep 28, 2026, 2:56:04 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
